Performance and Usability Evaluation of a Pattern-Oriented Parallel Programming Interface for Multi-Core Architectures

Multi-core architectures have increased the power of parallelism by coupling many cores in a single chip. This becomes even more complex for developers to exploit the available parallelism in order to provide high performance scalable programs. To address these challenges, we propose the DSLPOPP (Domain-Specific Language for Pattern-Oriented Parallel Programming), which links the pattern-based approach in the programming interface as an alternative to reduce the effort of parallel software development, and achieve good performance in some applications. In this paper, the objective is to evaluate the usability and performance of the master/slave pattern and compare it to the Pthreads library. Moreover, experiments have shown that the master/slave interface of the DSL-POPP reduces up to 50% of the programming effort, without significantly affecting the performance.
